Not the fellow you're replying to, but I've also read both books. I enjoyed The Player of Games very much. Three Body Problem was also good, but I found some characters to be frustratingly irrational (i.e., it feels like some people were doing things simply because the plot needed a character to do that action, rather than out of any meaningful motivation). Still worth your time - the Chinese cultural background was an interesting touch for me. I've not read the two sequels, but they also sound interesting.
